IronPlanet, an online marketplace for selling and buying used equipment and other durable assets, has announced that its GovPlanet marketplace will hold its latest “All-Humvee” online auction sale of US Army and US Marine Corps Humvee vehicles on Tuesday, Nov. 15.

In addition to a selection of US Army Humvees, GovPlanet is also featuring an opportunity for civilians to purchase a US Marine Corps M1123 Humvee. These specialty units are demilitarized and outfitted for sports and outdoor enthusiasts.

AM General manufactured the M1123 Humvee for the US Marine Corps primarily as cargo or troop transports and several have very low mileage. Known for the Optimizer 6500 engine, this model produces 205 hp and 440 ft-lbs. of torque. Other features include improved steering wheels, brakes, and bumpers as well as the capability to transport up to 4,400 lbs.

A portion of the proceeds from the online auction will be donated to Fisher House Foundation, a charity that primarily supports a network of comfort homes where military and veterans’ families can stay at no cost while a loved one is receiving treatment. The Foundation also manages a grant program that supports other military charities and scholarship funds for military children, spouses and children of fallen and disabled veterans.

The auction features more than 400 Humvees. IronPlanet also offers Humvee buyers the opportunity to acquire a Form SF97, the U.S. government-issued certificate that proves ownership and enables vehicle buyers to procure titles in states that allow it.
